Parramatta River Estuary Coastal Zone Management Plan Prepared for Parramatta River Estuary Management Committee

5 IMPLEMENTATION STRATEGY AND ACTION PLANS

5.1 Implementation Strategy

The full list of prioritised management actions has been developed into an implementation strategy that forms the basis of the Parramatta River Estuary CZMP. There are a total of 67 management actions in the strategy, of which 21 are to be progressed by the Committee as a whole. The remaining 46 management actions are the responsibility of individual authorities. It should be noted that implementation of these actions are dependent on suitable funding and internal resources being available within the individual organisations. In addition, a further 16 management actions were identified as generic actions of significant benefit or high priority that may be implemented by any council or authority in the event the necessary resources become available. These generic actions have been provided as a stand-alone list as they cannot be coasted or prioritised along with the other actions in the strategy.

Where possible, the management actions have also been mapped and the corresponding GIS (Geographic Information System) file provided to the relevant authority responsible for implementation. The locations of management actions have been mapped using GIS layers prepared for the Estuary Processes Study (AECOM, 2010) where relevant, and also GIS layers created by Cardno.

5.1.1 Cost of Implementation

The estimated capital cost of implementation of the Plan is $19.4 million, with an estimated $1.6 million in annually recurrent costs over an assumed ten year period of implementation (corresponding to the first period of implementation). The cost of implementation has been broken down for the different authorities in Table 5.1.

For some actions, the capital cost relates to preparation of a plan, an investigation or time for a staff member to progress an activity (project management). In other cases, the capital cost involves on the ground works, which is highly variable depending upon the specific project. The annually recurrent costs may relate to ongoing project management, maintenance or an annual budget for implementation of a staged strategy.

Table 5.1: Preliminary Indicative Cost of Implementation of the Implementation Strategy Authority Estimated Capital Cost Estimated Annually Recurrent Cost Ashfield Council $ 300,000 $ 4,000 Auburn City Council $ 78,750 $ 10,525 City of Canada Bay $ 4,193,375 $ 20,900 City of Ryde $ 1,312,918 $ 15,686 Hunters Hill Council $ 395,000 $ 416,125 Leichhardt Municipal Council $ 2,218,150 $ 45,700 Parramatta City Council $ 575,000 $ 97,000 Strathfield Council $ 5,237,250 $ 125,876 RMS (Maritime) $ 290,000 $ 7,000 SOPA $ 10,000 $ 134,500 Sydney Water $ 2,289,275 $ 163,063 Committee $ 2,473,000 $ 516,500 TOTAL $19,372,838 $1,556,875

As of 11 April 2013, the OEH website states that projects which can be subsidised under the coastal and estuary management programs include:

Preparation (or updating) of CZMPs and associated technical studies (including coastal hazard assessments); Action to manage the risks from coastal hazards; Action to implement environmental repairs, including habitat restoration and conservation projects; Pre-construction activities for projects that are eligible and are likely to proceed to construction; and Development of management tools (such as education projects). Funding of up to 50% of a project’s costs may be provided to successful grant applicants.

Other sources of grant funding include:

NSW Government Environment Trust and Heritage Grants Program; NSW DP&I’s Metropolitan Greenspace Program, Planning Reform Fund, and Sharing Sydney Harbour Access Program; NSW DPI Habitat Action Grants; RMS (Maritime)’s Better Boating Program; and Australian Government’s Caring for Our Country Program and Stormwater Harvesting and Reuse grants. Organisations like the HNCMA also play a role in working with local councils and community groups to undertake natural resource management projects.

5.1.2 Sub-Plans

In order to support the implementation strategy and identify where activities are proposed, a series of sub-plans have been developed, including Action Plans and ‘Process’ Sub-Plans. The Action Plans developed are discussed further and provided in Section 5.2.

A series of A3 ‘Process’ Sub-Plans (provided in Appendix G) have been developed to map those management actions for each of the processes listed below. These Sub-Plans are useful for showing in a more holistic fashion the spatial distribution of different types of activities across the study area:

Land Use Planning and Development (Figures F.1A and B), Water and Sediments (Figures F.2A to D), Estuarine Ecology (Figures F.3A to C), Bank Condition (Figures F.4A and B), and Human Usage and Recreation (Figures F.5A and B).

5.2 Action Plans

In order to support the implementation strategy and identify where activities are proposed, a series of Action Plans have been developed as sub-plans.

An Action Plan has been prepared for each authority consisting of a table listing the actions for implementation and capital and annually recurrent costs. Where possible, an A3 sized plan has also been provided that maps any location specific actions. The Action Plans can be easily separated out from the main report and used to progress implementation of each authority’s management actions. One Action Plan has been developed for each of the 11 authorities as well as the Committee:

Ashfield Municipal Council (2 actions); Auburn Council (2 actions); City of Canada Bay (5 actions); City of Ryde (5 actions); Hunters Hill Council (5 actions); Leichhardt Municipal Council (5 actions); Parramatta City Council (5 actions); Strathfield Council (5 actions); RMS (Maritime) (4 actions); SOPA (4 actions); Sydney Water (4 actions); and Committee (21 actions). Action Plan tables for the above-listed authorities are provided in Tables 5.2 to 5.13, respectively, while Action Plan maps are provided in Figures 5.1 to 5.10, with the exception of RMS (Maritime) and the Committee where no map has been prepared due to a lack of site-specific actions.

Note that the Committee has an overarching responsibility to progress the Plan and support its members in implementing actions for which they are responsible.

In addition a further 16 management actions were identified as generic actions. As previously discussed, these generic actions have been provided as a stand-alone list. The Action Plans for the additional 16 General Actions are provided in Table 5.14.
